velocity n. 1.迅速;快速。 2.速度,速率。 3.周轉(zhuǎn)率。 at a velocity of 100 miles per hour 用每小時一百英里的速度。 dart off with the velocity of a bird 像鳥一樣迅速飛跑過去。 drag-free velocity無阻力飛速,真空飛速。 escape velocity(克服地球引力的)第二宇宙速度,逃逸速度。 final velocity (發(fā)射物的)終速。 initial [muzzle] velocity(發(fā)射物的)初速[腔口速度]。 uniform [variable] velocity勻[變]速。
With appropriately selecting the partitioned generalized velocity , the bridle between the parachute and payload can be considered as elastomer or rigid body in a single simulation program . it is presented a general research method for analysis of different parachute - payload systems 選擇合適的廣義速度坐標(biāo),在同一個仿真程序中,可以將降落傘和載荷之間的連接帶考慮成剛性或是彈性的,且為不同的物傘系統(tǒng)的分析提供了通用的研究方法。
In the task space , the attitude space of the robot end - effector is parameterized by rodrigues parameters , and an output feedback controller without the generalized velocity is designed for controlling the position and attitude of the end - effector of a rigid robot 利用機器人控制系統(tǒng)固有的無源性,在作業(yè)空間中,采用rodrigues參數(shù)描述末端執(zhí)行器的姿態(tài),設(shè)計了用于機器人末端執(zhí)行器位姿控制的輸出反饋控制律,消除了控制器中的廣義速度。
